Top 10 Foods Highest in Copper


Copper is an essential trace mineral required by the body for energy production, absorption of iron, bone and connective tissue production, immune system function, synthesis of some hormones and red blood cell formation. (1) It also forms part of one of the body’s key antioxidant enzymes superoxide dismutase (SOD).
A deficiency in copper can lead to weak bones, joint pain, vitamin b12 deficiency, iron deficiency, and anemia. (2)
Conversely, over-consumption of copper will lead to cramps, diarrhea, and vomiting in the short term, and can have neurological (mental) effects in the long term. (3)
High copper foods include seafood, mushrooms, tofu, sweet potatoes, sesame seeds, cashews, chickpeas, salmon, dark chocolate, and avocados. (4) The current daily value (% DV) for copper is 0.9mg. (5)
